Patented July 24, 1906.

Application filed May 23, 1904. Serial No. 209.156.

To all whom it may concern.-

Be it known that I, ORVEY PRICE, a citizen of the United. States,residing in Plainfield, in the county of Union and State of New Jersey,have invented certain new and useful Improvements in Safe-Door-OperatingMechanism, of which the following is a specification.

This invention relates to bolt mechanism for safes or vaults, the objectof the invention being to provide an improved system of safe or vaultdoor bolt mechanism.

Another object of the invention is the provision of improved means forblocking the bolt mechanism against retraction.

Another object of the invention is the provision of improved means foroperating such bolt mechanism.

Another object of the invention is the provision of improved boltmechanism effectively locked and blocked by independent means, theoperation of which independent means and the actuation of the boltmechanism itself being obtained through the medium of a sin le spindlesupported independ ently of the blocking means.

A further object of the invention is the provision of an improvedbolting mechanism the bolts of which are effectively wedged in theirprotracted position without swinging such bolts and dogged and blockedin such position against retraction and which mechanism is simple in itsconstruction, organization, and operation, but powerful in its ac tion.

In the drawings accompanying and forming a part of this specification,Figure 1 is a rear view of the safe or vault door with its back plate inposition, the bolting mechanism being shown in dotted lines. Fig. 2 is across-sectional view taken in line a a, Fig. 1, the bolts being shownprotracted. Fig. 3 is a similar view to Fig. 2, but with the bolts shownretracted.

Similar characters of reference indicate corresponding parts in thedifferent figures of the drawings.

The present invention is in part an improvement upon the boltingmechanism patented by Henry D. I-Iibbard and in part an improvement uponthe doggingmechanism shown and described in the application of myselfand WValter Gaston, filed April 11, 1904, Serial No. 202,491, now PatentNo. 792,072, dated June 13, 1905:

The present improvement is designed in part to provide a boltingmechanism in which the bolts may be shifted lengthwise or radially intotheir protracted position in such manner that a powerful wedging actionthereof is obtained without the necessity of swinging the bolts in orderto accomplish this desirable result whereby the door will be drawnfirmly to its seat and wedged therein, while the bolts when in suchposition will be dogged and blocked against retraction by vibration orotherwise and which bolts should the actuating means be displaced willstill be maintained in their locking position against retraction.

The door 2 maybe of various constructions, but in the preferred formshown it is a one piece or integral circular structure which will bepreferably formed of unmachineable metal, such as manganese steel, andcomprises a body 3, having a flange 4., the latter provided withbolt-openings 5 for the passage of radial bolts 6, the shanks or innerends of which are shown in the present instance guided by guidingdevices which act to maintain the bolts against displacement. For thispurpose when the door is made of unmachineable metalsuch, for instance,as manganese steel, which is hard and when heat-treated very tough.as itis not practicable to drill the same to provide threaded openings forscrews or bolts, the body of the door is shown fitted with amachineable-metal part, preferably in the form of a soft-metal insert 7,shown maintained in position by a wedge or wedges, such door-body havinga dovetailed recess 8 centrally located, in which the insert is located.A plurality of inserts could be used, if desired, in place of the singleinsert shown. Each bolt 6 comprises a head 9 and a shank 10, each sideofwhich shank is provided with a groove 11 for the reception of guidingblocks 12, forming tracks screwed or bolted to the soft-metal insert. Bythis means the bolts are maintained against sidewise movement, as wellas retained in position against displacement, during their in and outmovements. It will of course be obvious that the reverse of thisconstruction could be used, if desiredthat is to say, the guides ortracks could be formed on the bolts and the ways on the blocks.

In the present instance, as hereinbefore stated, the bolts are notshifted or swung 'sidewise in order to obtain the radial movementthereof, and consequently the boltheads may be fitted with precision inthe bolt-openings formed in the fiange of the-door and, in fact, may beground to a .matching fit.

For sliding the bolts improved means is provided, comprising a travelingmember or head 13. This traveling head is mounted upon a rotatable screw14, journaled upon a spindle 15, screwed into the soft-metal insert atone end and headed in the rear of the back plate 50 at the other end,preferably passing through a cap 16, fitting into an opening in the backplate and bolted to such back plate. FiXedly secured to this screw 14 isa pinion 17 for rotating such member to shift the traveling head.Pivotally secured to brackets 18,

carried by the back plate, is link mechanism comprising a plurality oflinks 19, one for each bolt. Each of these links has separableconnection with its bolt, the connection being such that on thedisplacement of the back plate under an explosive charge or otherwisethe links will be Withdrawn from the bolts without shifting such bolts.For this purpose the bolts and links are provided with protuberances 20and recesses 21, in the present instance the recesses 21 being formed inthe bolts, while the protuberances 20 are carried by the links, forminga oint somewhat similar to a ball-and-socket joint. Each of these linkshas a cam formation, being provided with a pair of cam-faces 22 and 23,cooperating with a pair of cam-faces 24 and 25, formed on the travelinghead, one of such faces, as 24, being wedge-shaped to engage the innerends of the bolts, which are inclined or beveled, as at 26.

Referring to Fig. 3, when the head or actuator, as it may be termed, ismoved toward the body of the door the inclined camface 24 engages thecam-face 22 of the link 19 and slowly but powerfully moves the links ontheir pivots to shift the bolts into their protracted positions, asshown in Fig. 2, and when such bolts have been partly forced home theinclined cam-face 24 of the traveler then comes into engagement wviththe in clined inner "ends 26 of the bolts and by such direct engagementforces the bolts outwardly with a wedging action, the bolt-recess in thejamb of the safe-body and the ends of the bolts being formed to securethis highly-important result. When such bolts are firmly seated home andthe traveler at rest, the rib or cam-surface 25 acts to block theretraction of such bolts. This traveling head is thus not only abolt-actuator but a bolt-blocking device. -On the reverse movement ofthe traveling head it first releases or unblocks the bolts and then bythe engagement of its'cam-face 25 with the cam-faces 23 of the linksshifts the bolts inwardly into their retracted position. (See Fig. 3.)From the foregoing it will be seen that this traveling head is anon-rotatable reciprocatory actuator effective indirectly through thelinks at one period to shift the bolts outwardly and to retract theminwardly and at another period by direct engagement with the bolts toforce them outwardly and wedge them in position and finally effective toblock the bolts by its direct engagement therewith against retractionand that, owing to the inclined or beveled surfaces of the travelinghead and the inner ends of the bolts, such bolts will be forced home andheld in such position with the door wedged in its jamb against thepossibility of inserting nitroglycerin into the joint around such door,and thus insure a fluid-tight oint. For the purpose of shifting thistraveling head a spin dle 93, projecting through the body of the doorand located at one side of, and therefore independently of, thetraveling head, is provided. gear 27, preferably formed as one member ofa clutch 35, the spindle having its inner end mounted in a cap 28,bolted to the back plate 50. This gear 27 is in mesh with another gear29, mounted on'a stud 30, projecting from the back plate, and whichlatter gear is in mesh with the pinion 17, fixedly secured to the screwon which the traveling head is mounted. The other member 36 of thisclutch is splined to the spindle for rotation therewith, and when saidclutch members are in engagement the rotation of the spindle willthrough the medium of the gearing rotate the screw, and thus shift thetraveling head to actuate the bolts.

For the purpose of shifting the splined clutch member 36 into and out ofengagement with the loosely-mounted member 35 a clutch-shifter 37 isprovided, it being con nected to a short rock-shaft 38, to one end ofwhich the clutch-shifter is secured and to the other end of which alever 39 is connected,

On this spindle is loosely mounted a the opposite end of which ispivoted to the bolt 40 of the combination-lock 60, so that when thecombination-lock tumblers =..re properly set and the bolt 40 shifted theclutch-shifter will be operated to throw the splined clutch member 36into engagement with the loosely-mounted clutch member Then on therotation of the spindle the traveling head will be moved to shift thebolts.

For the purpose of adding additional security to the safe or vault adogging mechanism independent of the blocking means is provided. Thisdogging mechanism is substantially similar to that shown and describedin the joint application hereinbefore referred to, it comprising aplurality, preferably one for each bolt, of rotatable bolts 7 O,threaded into soft-metal inserts 71, fitted in the flange 4 of the door,so that it comprises what may be properly termed rim dogging mechanism.The outer ends of these bolts carry pin-ions 7 2 in mesh with the teeth73 of a gearring 7 4, supported by the door, in the present instance bymeans of the back plate 50, from which project a series ofantifriction-rolls 75, working in a track or way 76, located on theinner side of such gear-ring 7 4. By this means the ring is not onlysupported, but its rotary movement facilitated. For rotating thisgear-ring it is provided on its interior with teeth 7 7, which are inmesh with the gear 27, loosely mounted on the spindle 93. Each of thedoor-locking bolts is provided with a tapered opening 78, into which thetapered end 79 of its dogging-bolt fits. From the foregoing it will beseen that on the operation of the single spindle, which is shown taperedand tightly fitting into an opening in the door-body, being wedgedtherein by a threaded and pinned collar 80, the gear-ring will berotated, provided the clutch members are in engagement, through themedium of the gear 27 to rotate the dogging-bolts, and at the same timethe gear mechanism connecting this spindle with the screw onwhich thetraveling head is mounted will be operated to shift the traveling head.

The dogging-bolts and the traveling head are so organized and timed thatsuch doggingbolts will enter the openings in the lockingbolts at theproper moment and will be withdrawn therefrom before the bolts areretracted by the traveling head, as will be readily seen from aninspection of Fig. 2, since the traveling head must move from theposition shown into position to enga 'e the cam-surfaces 23 of the linksbefore said bolts are started. During this movement the dogging-boltsare rotated and withdrawn.

In order to prevent any possible premature withdrawal of thedogging-bolts or shifting of the traveling head, and thus unlock themain bolts, suitable locking means is provided. In one form it is shownin the nature of detent mechanism comprising a pair of locking fingersor detent's, one for locking the dogging mechanism and the other forlocking the blocking mechanism against movement. Both of theselocking-fingers are preferably operative at the same time and by thesame means, in the present instance by the combinationlock. For thispurpose an arm 85 is pivotally mounted on the bracket which car ries theclutchshifter rock-shaft, one end of which arm is connected with aprojection 86, carried by such rock-shaft,the other end carrying a shortshaft 87, to the free end. of which is secured a detent device 88,adapted to engage a part of the blocking mechanism, shown in the presentinstance as the pinion 17, fixed to the screw, such detent deviceprojecting between the teeth thereof, and thus preventing rotation ofsuch pinion, and thereby movement of the screw and the traveling head.Also connected to this pivoted arm 85 is a lever 89, connected at itsopposite end with a spring-actuated detent 90, working in a recess 91 ofthe flange of the door. This detent device in its normal operativeposition projects into a recess 92 of the gear-ring, and thus preventsrotation thereof. On the proper setting of the combination-lock themovement of the bolt thereof shifts the splined clutch member 36 intoengagement with the loosely-mounted clutch member 35 on the spindle, andat the same time the means just described operates to withdraw thedetent device 88 from the gear 17 and to shove the gear-ring detent 90inwardly against the action of its spring, and therefore away from thegear-ring, thus simultaneously releasing both the pinion and thegearring, so that on the turning of the spindle at this time both thegear-ring and the pinion 17 will be operated to release the doggingboltsand unblock the main bolts and retract such bolts to permit the door tobe opened.

Since the movement of the traveler is limited at one point by the bodyof the door and at the other point by the gear 17 and as this traveleris shifted through the medium of the spindle and the gear carriedthereon and as this gear also operates the gear-ring, it follows thatthe movement of the rotary dogging-bolts is also limited, so that suchbolts must necessarily have a certain limited movement and cannot,therefore, be rotated into position where they would fail to cooperatewith the main bolts at the proper time. Furthermore, the taperedrecesses in the main bolts and tapered ends of the rotating boltscooperate in such manner that the doggingbolts will properly fit intosuch main bolts at a predetermined period, or if they should not thecooperating tapered surfaces will enable the dogging-bolts to work theirway into proper position.

From the foregoing it will be seen that the same spindle which iseffective to operate the main bolts is also effective to control thedog- IIO . dogging the gear-ring.

ging and blocking of such bolts, so that this main bolt locking andblocking means is controlled by a single spindle, while at the same timea very powerful and effective boltoper ating means is provided and whichmeans cannot be vibrated so as to shift the main bolts from theirprotracted positions if perchance the back plate and operating meansshould be displaced or blown inwardly into the body of the safe underthe action of high explosives, for, as will be seen, the back plate, thetraveling head, and connectinglinks could all be displaced, togetherwith the gear-ring, but the rotary dogging-bolts would still lock themain bolts against retraction.

In conclusion it is to be understood that the various details may bemore or less changed without departing from the spirit or scope of thisinvention. For instance, the screw upon which the traveling head movesmay be so secured in position that the displacement of the back plate byan explosive charge or otherwise would not interfere with such head, asthe outer end of the bolt now supported by the cap which is bolted tothe back plate may be supported on the inner side 01 such plate in somesuitable manner, so that when the back plate is displaced the oppositeend of the bolt, being supported in the soft-metal insert, wouldmaintain the blocking member in position to assist securing the boltsagainst retraction.

In Figs. 12 and 13 is shown what I consider a very desirable dogging orlocking means for the traveling head and gear-ring, which dogging orlocking means, like that hereinbefore described, are simultai'ieouslyoperated through the medium of the clutchshifter and combination-lock ina manner previously set forth. This means, however, instead ofcomprising a detent mechanism can be more properly considered a stopmech anism, since it includes a plurality of stop devices. A rock-shaft95 is suitably supported. in position by the back plate and is providedat one end with a locking stop or lug 96, shown in the form of acrank-arm projecting into position to engage one of several projectionsor stops 97, carried on the inner side of the gear-ring. Then these stopmembers are in engagement, further rotation of the ring is prevented.The ring is provided with a number of these projections 97, so that someone of them may come into engagement with the stop-arm at the propertime. The foregoing comprises the stop mechanism for The stop mechanismfor dogging the traveling head comprises a disk 98, having a pluralityof projections or stops 99, this disk being fixed either to the .screwupon which the traveling head is mounted or fixedly secured to thepinion or gear 17. Cooperating therewith and ca ried by the rock-shaft95 is a stop or stop-arm 100, which when the stop devices 96- and 97 ofthe gear-ring and rock-shaft are in engagement are also in engagement toprevent the rotation of the screw. On the proper manipulation oftheclutch-shifter the rock shaft will be rocked and the stops 96 and 100thrown out of engagement with the stop devices 97 and 99 to permit thegear-ring and screw to be rotated.
